Abstract
The utility model discloses a mobile phone vibrator. The mobile phone vibrator comprises a vibration motor and an eccentric wheel; the vibration motor includes a driving shaft for driving the eccentric wheel, and a shell; the shell is provided with a supporting frame; a driven shaft which is coaxial with the central axis of the driving shaft passes through the supporting frame; one end of the driven shaft, which is far away from the vibration motor, is fixed to the eccentric wheel; a buffering device is arranged between the other end of the driven shaft and the driving shaft; and the buffering device comprises a shaft coupling sleeve which is connected with the driven shaft and the driving shaft; and the shaft coupling sleeve has elasticity. The driving shaft of the vibration motor is connected with the driven shaft through the shaft coupling sleeve with elasticity, wherein the driven shaft fixes the eccentric wheel, and the driven shaft is fixed through the supporting frame, and therefore, an centrifugal force generated by the eccentric wheel can be prevented from being directly applied on the driving shaft, and thus, impact of external forces which is borne by the internal structure of the vibration motor can be decreased, and the service life of the vibration motor can be prolonged.
